  • 목적: 근골격계 종양의 종류에 따른 케모카인 발현 양상을 보고, 원발성 골육종과 재발된 골육종, 골육종의 항암화학요법 전과 후의 발현 차이가 있는지를 조사하고자 한다. 대상 및 방법: 종양조직을 얻을 수 있었던 원발성 양성 및 악성 근골격계 종양 10예, 재발된 골육종 1예, 화학요법 후의 골육종 1예 및 정상조직의 대조군 1예를 대상으로 하였다. RNA를 분리한 다음, 역전사 중합효소 연쇄반응(RT-PCR )과 RNase protection assay (RPA)를 이용하여 싸이토카인과 케모카인의 발현을 조사하였다. 각각의 종양간에 발현도 차이가 있는지를 알기 위하여 SPSS를 사용한 Fisher's exact test를 이용하여 통계적 처리를 하였다. 결과: IL-8과 TNF-${\alpha}$는 모든 조직에서 발현되었고, IFN-${\gamma}$는 2예 외에 모두 발현하였으며, RANTES의 경우 연부조직 종양 5예, 골종양 4예에서, GRO${\alpha}$는 연부조직 종양 1예, 골종양 2예에서 발현되었고, MCP-1과 IP-10의 경우 악성 골종양군에서는 2예만, 나머지에서는 모두 발현되는 다양한 양상을 보였다. 원발성 골육종에 비해 재발된 골육종 조직에서의 발현은 IFN-${\gamma}$를 제외하고, 전반적으로 발현도가 훨씬 강하였으며, 모든 종류의 케모카인 및 사이토카인들이 발현되었다. 화학요법 후에는 RANTES와 IFN-${\beta}$만이 발현되었으며, TGF${\beta}$ isoform 중 TGF${\beta}_1$ 유전자의 발현만 관찰되었다. 결론: 대상의 수가 적어 통계적 분석을 통한 정확한 자료의 제시는 불가능하였으나, 연부조직 종양과 골종양에 있어 일부 케모카인 및 사이토카인의 발현 차이가 있음을 확인하였고, 골육종의 경우 IFN-${\gamma}$ 및 TGF-${\beta}$ isoform의 발현 분석이 종양의 재발과 치료 후 변화에 대한 지표에 응용될 가능성이 있음을 제시하였다.

  • 창업은 국가경제 활성화와 기술 산업화를 용이하게 하고, 지역경제의 활성화를 높여 그 중요성이 강조되고 있다. 특히 창업보육 시스템은 경제 활성화를 위한 정책의 일환으로 창업 초기기업의 성장을 위해 물리적 및 비물리적 서비스를 제공하며 초기기업들의 성장을 위해 많은 역할을 하고 있다. 본 연구는 서울에 위치한 창업보육센터 입주기업 CEO의 기업가정신 및 시장지향성이 경영성과에 어떠한 영향을 미치는지를 분석하고, 창업보육센터의 지원서비스가 경영성과에 어떠한 조절효과를 갖는지 살펴보았다. 이러한 연구의 검증을 위해 국내 BI협회에 등록이 되어있고 서울에 위치하고 있는 9개 창업보육센터 입주기업을 대상으로 온라인 및 오프라인 설문 320부를 배포하여 127부를 회수하였고, 이 중 불성실한 응답의 설문지를 제외한 117부를 통계분석에 활용하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 창업보육센터 입주기업 CEO의 기업가정신 하위변수인 혁신성, 진취성, 위험감수성 중 진취성이 경영성과의 재무적 성과와 비재무적 성과에 영향을 미치는 것으로 나타났다. 둘째, 시장 지향성의 하위변수인 고객지향성, 경쟁자 지향성, 협력지향성 중 경쟁자 지향성이 경영성과의 재무적 성과와 비재무적 성과에 영향을 미치는 것으로 나타났다. 셋째, 물리적 지원서비스 활용정도는 진취성과 재무적 성과간의 조절작용을 하고, 진취성과 비재무적 성과에 조절작용을 하는 것으로 나타났다. 마지막으로, 시장지향성과 경영성과 간의 관계에서 비물리적 지원서비스 활용정도가 협력지향성과 재무적 성과간의 조절작용을 하는 것으로 나타났다. 진취적인 성향을 가지고 있는 창업보육센터 입주기업 CEO에게 사무지원, 마케팅 지원, 입주기업 간의 네트워크 구축, 교육, 법률, 회계, 세무 등 비물리적 지원서비스를 제공해준다면 고용증가, 종업원의 업무 수행능력, 종업원의 만족도 등 비재무적성과가 더욱 향상될 것이라고 기대할 수 있다. 또한, 협력의 문화를 가진 기업이 사무지원, 마케팅 지원, 입주기업 간의 네트워크 구축, 교육, 법률, 회계, 세무 등 비물리적 지원서비스를 활용한다면, 기업의 매출 증대, 순이익 증가, 고객의 충성도 및 시장점유율이 더욱 향상될 것이라고 기대할 수 있겠다. 기존의 창업보육센터 관련 연구들은 주로 창업보육 매니저의 역량에 관한 연구를 중심으로 이루어지고 있으며, 입주기업의 지원서비스와 기업의 성과에 대한 연구가 부족하였는데 본 연구를 통해 향후 BI 입주기업의 성장과 자생력을 높일 수 있는 기초 자료로 활용 가능하리라 기대한다.

  • It is not too much to say that smartphones have become an essential part of our lives due to their versatility. Nevertheless, they still have less overall capabilities than their desktop counterparts. Specifically, they have small screens and low resolutions, which make their applications difficult to have a usable interface. To account for these limitations, the interface of smartphone applications should be designed carefully and properly. Good interface design to any application is critical. However, a comprehensive information systems (IS) literature review found that there has been little research on the user interface design of smartphone applications. More specifically, there has been little empirical evidence and understanding about how metaphors, an imaginative way of describing objects and concepts, in the user interface of smartphone applications affect users' intention to use the applications. Thereby, the research goals of this study are to examine 1) the effects of the metaphors in the user interface of smartphone applications on the interaction between users and applications and 2) the effects of mediating variables including the interaction between users and applications, users' beliefs and attitudes, on users' intention to use the applications. A survey was conducted to collect data. University students and practitioners participated in the survey. A 24-item questionnaire was developed on a 5-point Likert-type scale. The measurement items were mostly adapted from the previous studies in the IS literature and modified to fit the context of this study. First, a principal component factor analysis was performed to explore the inter-relationships among a set of variables. The analysis showed that most of the items loaded quite strongly on the six components. The analysis also revealed the six components with eigenvalues exceeding 1, explaining a total of 70.7 per cent of the variance. The reliabilities of the items were also checked. Most Cronbach alpha values were above 0.8, so the scales were considered reliable. In sum, the results of the analysis support the decision to retain the six factors for further investigation. Next, the structural model was analyzed with AMOS structural equation modeling. The values of GFI, AGFI, NFI, TLI, CFI, and RMSEA were checked. The values showed that the research model considerably have a good fit in general. Next, the convergent and discriminant validities of all constructs were examined. The values for the standardized regression weights and critical ration (CR) indicated sufficient convergent validity for all constructs. In addition, the square root of the average variance extracted (AVE) of each construct was compared with its correlations with all other constructs. The results supported discriminant validity for all constructs. In sum, the results of analysis demonstrated adequate convergent and discriminant validities for all constructs. Finally, path coefficients between the variables were examined. Methphor was found to have an impact on interaction (${\beta}$ = .457, p = .000). There were also significant effects of the interaction on perceived usefulness (${\beta}$ = .273, p = .000) and ease of use (${\beta}$ = .405, p = .000). User attitude was significantly influenced by these two beliefs, perceived usefulness (${\beta}$ = .386, p = .000) and ease of use (${\beta}$ = .347, p = .000) respectively. Further, the results of analysis found that users' intention to use smartphone applications was significantly influenced by user attitude (${\beta}$ = .567, p = .000). Based upon the analyses, all hypotheses were supported. This study found that the metaphors used in the interface of smartphone applications affect not only the interaction between users and applications, but also users' intention to use the applications through the mediating variables, perceived usefulness and ease of use. These findings imply that if the metaphors used in the user interface of application are easy enough to understand for smartphone users, then the application can be perceived useful and easy to use, which in turn make users to have an intention to use the application. In conclusion, this study contributed not only to validate and extend Technology Acceptance Model (TAM) partially, but also to develop the construct of metaphor in smartphone settings. However, since a single empirical study cannot be enough to validate the findings, some limitations should be considered.

  • 본 연구는 기술창업기업의 특허활동이 초기기업 성과에 미치는 영향에 대한 연구이다. 기술창업기업은 혁신적인 기술을 바탕으로 새로운 제품 또는 생산방식의 도입과 시장개척을 추구한다는 점에서 지식재산권, 특히 특허권과 밀접하게 관련이 있으며, 그러한 혁신적 기술이 기업 설립과 운영의 핵심적인 역할을 한다는 점에서 기술창업기업에서 특허활동이 가지는 역할에 대한 연구는 중요한 의미가 있다고 볼 수 있다. 기존의 연구들은 기업의 특허활동과 관련하여 정량적인 특허지표를 사용하여 기업 경영성과에 미치는 영향을 파악하는 것이 대부분이어서 기업에서 실제 특허와 관련하여 행해지는 특허활동에 대한 연구는 취약한 실정이었다. 따라서 본 연구를 통해 기술개발지원활동, 권리화 활동, 침해대응활동, 기반활동 등 기업의 특허활동이 신제품개발, 즉 기술성과와 제품성과를 거쳐 경영성과로 이어지는 인과관계를 다음과 같이 검증하였다. 먼저, 특허활동은 기술성과와 제품성과에 긍정적 영향을 미치고 있다. 즉, 특허의 취득과 활용에 관련된 제반활동들이 기업의 신제품개발, 그중에서도 기업의 신기술 개발이나 특허 획득률 등 기술성과에 더 큰 영향을 미치고 있음을 확인하였다. 둘째, 기술성과는 제품성과에 긍정적 영향을 미치고 있으나, 경영성과에는 긍정적 영향을 미치고 있지 않다. 다만, 본 연구의 가설과 모형의 실증분석 결과, 직접적은 아니지만 제품성과를 거쳐 간접적으로 경영성과와 상관관계가 있는 것으로 나타났다. 셋째, 제품성과는 경영성과에 긍정적 영향을 미치고 있다. 결론적으로 특허활동이 기업의 경영성과에 영향을 미치고 있음을 확인하였으며, 기업의 특허나 기술의 개발과 같은 기술성과도 중요하지만 결국 기업에 있어 지속적인 경영성과 창출은 제품성과, 즉 고객이 필요로 하는 제품을 만들어 판매함으로써 가능하다는 것을 재확인할 수 있었다.

  • The importance of the health care for the miners not only concerns the productivity of the enterprises but also as a fundamental human right, it has to be secured and protected by the society and the government. The Korean coal miners began to find their works at overseas since 1963 when the Korean government selected and dispatched its miners to West Germany. As years go by, the demand and the supply of the coal miners, the program of the coal miners health care became the important tasks to be solved and the further studies and research were necessary to support these tasks achievement. The writers made a statistical analysis on health status of the 1,559 Korean applicants applying for the coal miners in West Germany during the year of 1972 and 1973 by the using of the data of physical examination which were directed by the Korea Overseas Development Cooperation. The standard of physical examination which was applied for coal miners applying the jobs in West Germany was authorized by the Government Office of Labor in 1967. The results are as following; 1. The applicants were from the various provinces throughout Korea; Gang Weon 50.2%, Jeon-Nam 16.8%, Chung-Nam 13.7%, Gyeong-Nam 10.5%, City of Seoul 5.4%, and others 3.7%. 2. The ages of the applicants were from 20 to 44. The age group of 25-29(36.3%) and of 30-34(55.2%) together occupied the 91.5 per cent of the total applicants. 3. Among the 1,559 applicants 52.1 per cent passed the physical examinations. The tendency were shown that as the age increased, the passing rate decreased, and the married applicnts had lower passing rates compared to the unmarried applicants. 4. The height of the applicants averaged $168.4{\pm}4.74(cm)$ and the weight averaged $61.3{\pm}5.65(kg)$. 5. The average vision of the left eye of the applicants was $0.92{\pm}0.23$ and the right eye was $0.91{\pm}0.30$. 6. The mean value of the systolic blood pressure of the applicants was $145{\pm}13(mmHg)$ and the diastolic blood pressure was $85{\pm}8(mmHg)$. 7. Fifteen hundred and fifty-nine applicants were taken chest X-ray and 17.2 per cent were found abonrmal. For each 1,000 applicants, 46 Pulmonary calcification and fibrosis, 45 chronic bronchitis, 27 pleural thickening and adhesion, 20 pulmonary tuburculosis, 11 anomalies of the rib, 10 pulmonary infiltration and 21 others diseases were found. 8. Lumber X-ray examination showed that 23.9 per cent (372 applicants) were found abnormal. For each 1,000 applicants, 77 osteoarthritis, 56 lumbarization, 15 fracture of vertebrae, 15 spondyloarthritis, 14 deformity of vertebrae, 13 spina bifida, 12 sacralization, 12 spondylolysis, and 5 others diseases were found. 9. In total, 47.9 per cent of 1,559 applicants failed the physical examinations, and the main causes for the failure were shown to be 7.1% of anomalies of spine, 6.3% of osteoarthritis, 4.7% of pulmonary calcification and fibrosis, 4.6% of chronic brochitis, 3.6% of hypertension (only), 3.4% of fracture of vertebrae. 3.1% of underweight(under 57.0kg), 2.0% of spondyloarthritis, 2.0% oe pulmonary tuberculosis, 1.7% of pleurisy, 1.0% of spina bifida, 1.5% of syphilis, 1.5% of color blindess, and 1.0% of underheight(under 160.0cm).

  • A study on energy and protein utilization, and milk production of Bali cows on grass-legume diets was carried out using 12 first lactation cows (initial BW $263.79{\pm}21.66kg$) during a period of 16 weeks starting immediately post calving. The animals were randomly allotted into 4 dietary treatment groups R1, R2, R3 and R4, receiving from the last 2 months of pregnancy onwards, graded improved rations based on a mixture of locally available grass and legume feed ad libitum. R1 contained on a DM basis 70% elephant grass (PP, Penisetum purpureum) plus 30% Gliricidia sepia leaves (GS), R2 was 30% PP plus 55% GS supplemented with 15% Hibiscus tilliactus leaves (HT, defaunating effect), R3 and R4 were 22.5% PP+41.25% GS+11.25% HT+25% concentrate, where R3 was not and R4 supplemented with zinc di-acetate. TDN, CP and zinc contents of the diets were 58.2%, 12.05% and 18.3 mg/kg respectively for R1, 65.05%, 16.9% and 25.6 mg/kg respectively for R2, 66.03%, 16.71% and 29.02 mg/kg respectively for R3 and 66.03%, 16.71% and 60.47 mg/kg respectively for R4. Milk production and body weight were monitored throughout the experimental period. In vivo body composition by the urea space technique validated by the body density method and supported by carcass data was estimated at the start and termination of the experiment. Nutrient balance and rumen performance characteristics were measured during a balance trial of 7 days during the 3rd and 4th week of the lactation period. Results indicated that quality of ration caused improvement of ruminal total VFA concentration, increments being 52 to 65% for R2, R3 and R4 above R1, with increments of acetate being less (31 to 48%) and propionate being proportionally more in comparison to total VFA increments. Similarly, ammonia concentrations increased to 5.24 to 7.07 mM, equivalent to 7.34 to 9.90 mg $NH_3-N/100ml$ rumen fluid. Results also indicated that feed quality did not affect DE and ME intakes, and heat production (HP), but increased GE, UE, energy in milk and total retained energy (RE total) in body tissues and milk. Intake-, digestible- and catabolized-protein, and retained-protein in body tissues and milk (Rprot) were all elevated increasing the quality of ration. Similar results were obtained for milk yield and components with mean values reaching 2.085 kg/d (R4) versus 0.92 kg/d (R1) for milk yield, and 170.22 g/d (R4) vs 71.69 g/d (R1), 105.74 g/d (R4) vs 45.35 g/d (R1), 101.34 g/d (R4) vs 46.36 g/d (R1) for milk-fat, -protein, and -lactose, respectively. Relatively high yields of milk production was maintained longer for R4 as compared to the other treatment groups. There were no significant effects on body mass and components due to lactation. From the relationship $RE_{total}$ (MJ/d)=12.79-0.373 ME (MJ/d); (r=0.73), it was found that $ME_{m}=0.53MJ/kgW^{0.75}.d$. Requirement of energy to support the production of milk, ranging from 0.5 to 3.0 kg/d, follows the equation: Milk Prod. ($Q_{mp}$, kg/d)=[-2.48+4.31 ME($MJ/kg^{0.75}.d$)]; (r=0.6) or $Q_{mp}$=-3.4+[0.08($ME-RE_{body\;tissue}$)]MJ/d]; (r=0.94). The requirement for protein intake for maintenance ($IP_m$) equals $6.19 g/kg^{0.75}.d$ derived from the relationship RP=-47.4+0.12 IP; (r=0.74, n=9). Equation for protein requirement for lactation is $Q_{nl}$=[($Q_{mp}$)(% protein in milk)($I_{mp}$)]/100, where $Q_{nl}$ is g protein required for lactation, $Q_{mp}$ is daily milk yield, Bali cow's milk-protein content av. 5.04%, and $I_{mp}$ is metabolic increment for milk production ($ME_{lakt}/ME_{m}=1.46$).

  • This study is aimed at identifying the national economic value of the irrigation facilities by reviewing the existing papers on economic values of the irrigation facilities and presenting current status of dual O & M problems of the irrigation facilities. This study suggested the unified O & M system rather than continuing the existing dual O & M system of irrigation facilities based on the surveyed results of the activities of irrigation fraternities in Chungnam Province. The findings and proposals for the successful unified and mono O & M system of the irrigation facilities are as follows: (1) Total number of irrigation facilities in the nation accounts for 67,582, while the total length of irrigation and drainage canals amounted to about 174,259km. On account of the total length of structural canals was estimated at 31%, much losses of water and much O & M costs have been inevitable for the full irrigation rice culture. In spite of the past heavy investment for irrigation facilities, the ratio of rain-fed and partially irrigated paddy fields accounts for 23% in 2003. Both Korea Agricultural and Rural Infrastructure Corporation (KARICO) and the city and Gun Governments have managed the irrigation facilities separately by irrigation fraternities. The KARICO have commanded 59% of irrigation paddy area with 18% of the total irrigation facilities, while the city and Gun governments covered 41% of irrigation paddy area with 82% of the existing number of irrigation facilities representing small and medium scale. (2) The 1999 demand prices of irrigation water per ton expressed in 2000 constant market price was estimated at 388 won, the supply price was amounted to 184 won per ton. Considering the supply and demand curve of the irrigation water, the existing irrigation facilities could not satisfy the demand of irrigation water. (3) In 1999, total present added value of the irrigation facilities during the economic life accounted for 48 trillion won, while total supply cost was 44.7 trillion won. The marginal benefit and cost ratio of irrigation water was 1.08. (4) The total O & M cost per year amounting to 681.1 billion won have been required to maintain and repair the existing irrigation facilities in Korea. For the successful unified O & M of irrigation facilities covering whole irrigated paddy field in Korea, 950 billion won of O & M costs are required to keep up the marginal benefit of irrigation water as 2,800 billion won per year. The total O & M cost as 950 billion won should be allocated 40%, 380 billion won for O & M costs of irrigation facilities and 60%, 570 billion won for improvement of irrigation facilities. (5) The study investigated and reviewed the present O & M status of the irrigation facilities by small and medium irrigation fraternities. Most of the farmers belong to the irrigation fraternities preferred not only unified O & M but also KARICO take-over of the whole O & M activities of the irrigation facilities. The prevailing O & M cost per 10a expended by the Corporation was amounted to 104,890 won, while that of city and Gun governments was only amounted to 4,600 won per 10a. regarding the small amount of O & M cost expended by city and Gun governments, it is evident that the existing irrigation system have been managed ineffectively and deteriorated the facilities comparing that of KARICO. In conclusion, the Government could not satisfied the demand of irrigation water by suppling water with existing irrigation facilities. Therefore new additional investment and financial support for irrigation water development should be made to convert rain-fed and partially irrigated paddy fields into fully irrigated ones. The operation and maintenance cost should be supported to keep the marginal values of rice production of existing irrigation facilities in the national economy and to modernize the obsolete irrigation facilities. By unifying the existing dual O & M systems, all the farmers belong to the irrigated paddy fields have to be equally benefited and could be increased their farm income and be stabilized their rural lives.

  • The purpose of this study to investigate the awareness of environmental management knowledge and behavior and the effect of independent variables (The environmental management behavior of housewives are composed of five activities-clothing, eating, housing, buying, family management. The independent variables are composed of objective variable and subjective variable). The Research Questions are as follows; 1. Are there significant differences in the housewife's awareness of the environmental management knowledge according to the objective variable and the subjective variable? 2. How much are the effects of related variables on the awareness of environmental management knowledge? 3. Are there significant differences in the housewife's environmental management behavior according to objective variable and subjective variable and awareness of environmental management knowledge? 4. How much are effects of related variables on the housewife's environmental management behavior? For these purpose, a theoretical framework was developed by literature review and applied to empirical test. The data was collected through the questionnaire those respondents were 477 housewives in seoul. It was analyzed by various statistical methods such as Frequency. Percentile, GLM, F-test, T-test, Duncan's Multiple Range Test, Pearson's Correlations Analysis Simple Regression Analysis, and Multiple Regression Analysis. The results of this research are as follows; 1. The awareness of environmental management knowledge had significant differences according to the variables such as housewife's age, husband's job, family number, education experience of environment, frequencies of contracting mass media, the perceived adequacy of resources, social-altruistic orientation. 2. Among all of these variables affecting the awareness of environmental management knowledge, the perceived adequacy of resources had the highest effects and the next were family number, social-altruistic, type of residence in order. 3. Total Environmental management behavior of housewives had significant differences according to the variables such of environment, frequencies of contracting mass media, the satisfaction of household labor, the perceived adequacy of resources, biospheric orientation, social-altruistic orientation, egoism orientation, the awareness of environmental management knowledge.

In particular, the clothing, eating, housing, buying management behavior had significant differences according to the variables such as education experience of environment. And the housing, buying management behavior had significant differences according to the variables such as frequencies of contracting mass media. 4. Among all of theses variables affecting environmental management behavior, the most influence variables was awareness of environmental management knowledge and the next were influence of housewife's job, biospheric orientation, the satisfaction of household labor, education experience of environment, frequencies of contraction mass media, egoism orientation in order. Among all of theses variables effecting the clothing, eating, housing, buying management behavior the variables affecting the family management behavior, the most influences variables was housewife's job. In the result of analysing the housewife's environmental management behavior and awareness of environmental management knowledge, influences of education experience of environment had the highest effect and frequencies of contracting mass media may more influencial than other variables. And Concrete and systematic knowledge and technique of environmental education is requisite. The result of this study could be attributed to develop the efficient environmental information. More emphasis should be given to environmental education and a long range environmental policy. in particular, environmental education be effectively related to environmental behavior, life-education and systematic support must be provided.

  • 목적: 본 연구는 호스피스 자원봉사자들의 부담감 정도와 관련요인들을 파악함으로서 바람직한 봉사활동을 할 수 있도록 돕는 중재프로그램 마련에 기초 자료를 제공하는데 그 목적이 있다. 방법: 연구대상은 가톨릭대학교 부속 8개 병원에서 호스피스 자원봉사 활동을 하고 있는 봉사자 243명이었다. 연구도구는 설문지로서 부담감 측정도구(25문항)와 삶의 질 측정도구(47문항)를 사용하였고 자료처리는 SAS program을 이용하여 t-test, ANOVA, Duncan test, Pearson's correlation coefficient로 분석하였다. 결과: 1. 조사 대상자 중 50대 연령군이 44.0%, 여성이 85.6%, 고졸 학력이 51.9%, 기혼상태 86.8%, 중정도의 생활정도 85.6%, 무직인 경우 45.3%, 삶의 질이 보통인 경우 78.6%였다 2. 조사대상자의 주당 봉사 시간은 평균 5.0시간, 자원봉사활동기간은 평균 41.7개월 봉사 대상자 임종경험은 평균 13.9회, 자원봉사자 교육을 받은 횟수는 평균 12.8회이었다. 11.5%에서 가족 중 호스피스를 받은 적이 있었으며 봉사활동 시작 동기는 이웃에 봉사하기 위하여 35.0%였다. 조사대상자의 72.9%에서 자원봉사활동에 대해 만족하고 있었으며 90.4%에서 호스피스 봉사활동에 대한 가족들의 반응이 긍정적이라고 하였다. 47%에서 본인이 자원봉사로서의 자질이 적절하다고 답하였고 94.3%에서 자원봉사자 교육이 필요하다고 답하였으며 32.9%에서 호스피스 봉사활동 중 영성적 돌봄이 가장 어렵다고 답하였다. 3. 조사 대상자의 전체 부담감 평균 평점은 $53.3{\pm}10.4$이었다. 일반적 특성에 따른 부담감 정도는 각 특성별로 유의한 차이는 없었다. 4. 호스피스 자원봉사관련 특성에 따른 부담감 정도는 호스피스 봉사활동에 대한 가족들의 반응이 긍정적인 경우 유의하게 낮았으며, 봉사활동 유형에 따른 부담감 정도는 가족 돌봄, 신체적 돌봄에서 유의하게 높았다. 5. 각 영역별 부담감 정도는 환자 돌봄에 대한 부담감, 봉사 후 자아성취감에 대한 부담감, 봉사 활동에 대한 부담감의 순으로 높았다. 각 항목별 부담감 정도는 "환자나 보호자가 죽음을 어떻게 받아들일지 염려된다", "환자에게 최선을 다하지 못할 때 죄책감을 느낀다", "환자를 돌볼 때 긴장된다"의 순으로 높았다. 6. 부담감과 삶의 질과는 역상관관계가 있었다. 결론: 이상의 결과를 토대로 호스피스 자원봉사자들의 부담감을 감소시키고 효율적인 자원봉사를 할 수 있도록 돕기 위해서는 교육정도와 가족들의 지지정도 가장 어렵게 느끼는 봉사활동을 고려하고 특히 환자들의 가족 돌봄과 환자의 신체적인 돌봄과 관련한 교육을 강화하며 삶의 질을 높이기 위한 방안이 모색되어야 할 것이다.
